Base deficit in immediate postoperative period of coronary surgery with cardiopulmonary bypass and length of stay in intensive care unit.

Abstract

To assess the relationship between the base deficit value in the immediate postoperative period of coronary surgery for cardiopulmonary bypass and the length of stay in the ICU. Prospective descriptive study in the department of anesthesia and cardiovascular surgery of a university hospital. 185 consecutive patients. Coronary artery bypass graft with cardiopulmonary by pass. Thirty variables were determined during the pre-, intra-, and postoperative periods; a statistical univariate analysis was performed differentiating patients whose length of stay in the ICU was 2 days or less and those whose stay was more than 2 days. Secondly, a logistic regression model was performed on the variables shown to have a statistically significant difference in univariate analysis, with determination of the odd ratio. Fourteen variables had a statistically significant difference in univariate analysis and three of them highlighted by the logistic regression model: administration of catecholamines, base deficit value in the 1st h postoperatively, and age with odd ratios, respectively, of 3.15, 1.51, and 1.07). The value of base deficit measured during the 1st h after coronary surgery for cardiopulmonary bypass is correlated with the length of stay in ICU.
